oops, I hads uploaded the wrong file, here's the hopefully correct and last word on it
https://www.dropbox.com/s/05xl7ml171noyjq/convolution~.zip?dl=0 and my CPU load is actually at about 57%, not 50% The last file I uploaded was using a compiled object to perform the complex multiplication and that helped a little with the efficiency. I'm gonna use it for my non vanilla abstraction that I'm bringing into my ELSE library. cheers Em ter, 8 de jan de 2019 às 14:13, Alexandre Torres Porres <por...@gmail.com> escreveu: > Ok, here's the new deal... > > https://www.dropbox.com/s/l69gzv98g3th5d1/conv.rev~.zip?dl=0 > > there are two subpatches for testing, one is light with a relative big > window partition (1024) and a short Impulse Response (2 secs). > > The other is quite heavy, it's an 8 sec long IR with a window size of 512! > This one takes just a bit over 50% of my CPU power, and I'm on a last > generation macbook pro (2.6Ghz processor)... but I need to increase the > Delay (msec) from 5 to 10 in the audio settings, otherwise I get terrible > clicks! > > William Brent's convolve is ridiculously much more efficient, the same > parameters take about 14% of my CPU power and I can use a delay of 5 ms in > the audio settings. > > But anyway, this is useful for teaching and apps that implement a light > convolution reverb (short IR/not too short window) need pure vanilla > (libpd/camomille and stuff) > > Cheers! > > Em dom, 6 de jan de 2019 às 14:25, Alexandre Torres Porres < > por...@gmail.com> escreveu: > >> Meanwhile, I deleted the original file so people can't get it anymore :) >> >> Em dom, 6 de jan de 2019 às 14:16, Alexandre Torres Porres < >> por...@gmail.com> escreveu: >> >>> Hi, quick updates and developments over my weekend >>> >>> >>>> On Thursday, 3 January 2019, 04:19:50 GMT, Alexandre Torres Porres < >>>> por...@gmail.com> wrote: >>>> >>>> what you think, is it working? >>> >>> >>> So, the patch/algorithm was wrong and I've fixed >>> >>> >>>> Both objects on the help file take about 40% of my CPU power, but I'm >>>> on a wild machine >>>> >>> >>> I was able to do a few more things and make it much more efficient >>> >>> >>>> I tried the idea of having each partition work with FFT saved on >>>> tables, so we wouldn't need to perform FFTs in different instances of >>>> clone, but that doesn't seem to be possible. >>> >>> >>> This is because things were wrong, like I said, now that I've fixed it, >>> that was possible. >>> >>> But my current version is not vanilla anymore, as I'm developing this >>> object to include it in my "ELSE" library.
